编译项目时，出现以下错误消息：

Program type already present: com.google.android.gms.internal.measurement.zzabn Message{kind=ERROR, text=Program type already present: com.google.android.gms.internal.measurement.zzabn, sources=[Unknown source file], tool name=Optional.of(D8)}

要么

D8: Program type already present: com.google.android.gms.internal.measurement.zzabo

Firebase对SDK进行了更新：

Firebase Android SDK现在具有独立的版本号，可以进行更频繁，更灵活的更新。

更新所有Firebase依赖项以使用最新版本：

Firebase Core           com.google.firebase:firebase-core:15.0.2

Cloud Functions         com.google.firebase:firebase-functions:15.0.0
Cloud Messaging         com.google.firebase:firebase-messaging:15.0.2
Cloud Storage           com.google.firebase:firebase-storage:15.0.2

请同时更新google-services插件：

classpath 'com.google.gms:google-services:3.3.1'

您可以在这里找到最新的Google服务

还请检查此链接以了解更改，并按照文章中列出的步骤进行操作：

宣布新的SDK版本

就我而言，问题是相同的。我遵循以下步骤：

1.build.gradle（渐变）

变化：

  classpath 'com.google.gms:google-services:3.2.0'

至 ：

  classpath 'com.google.gms:google-services:3.2.1'

2.build.gradle（模块）

    implementation 'com.google.firebase:firebase-messaging:15.0.2'
    implementation 'com.google.android.gms:play-services-maps:15.0.1'

引起此问题的原因是Firebase开始分别对库进行版本控制。将所有内容更新到最新版本即可解决此问题。

当前将google play gradle插件版本更新为最新版本4.0.1。

在项目级别 build.gradle文件中：

classpath 'com.google.gms:google-services:4.0.1'

有关Google Gradle插件最新版本的信息，请访问：

https://bintray.com/android/android-tools/com.google.gms.google-services/

并在应用级文件中使用各个库的最新版本： build.gradle

implementation 'com.google.android.gms:play-services-vision:15.0.2'
implementation 'com.google.android.gms:play-services-ads:15.0.1'
implementation 'com.google.firebase:firebase-messaging:15.0.2'

有关各个库的最新版本的信息，请访问：

对于那些截至2018年11月8日使用最新Firebase版本面临此问题的人。我通过降级firebase-ads库而保留其余版本使用最新版本的方式来解决冲突。

我从：

googleImplementation "com.google.firebase:firebase-core:16.0.5"
googleImplementation "com.google.firebase:firebase-ads:17.0.0"  //CONFLICTING VERSION
googleImplementation "com.google.firebase:firebase-config:16.1.0"
googleImplementation "com.google.firebase:firebase-messaging:17.3.4"

至：

googleImplementation "com.google.firebase:firebase-core:16.0.5"
googleImplementation "com.google.firebase:firebase-ads:15.0.1"  //WORKING VERSION
googleImplementation "com.google.firebase:firebase-config:16.1.0"
googleImplementation "com.google.firebase:firebase-messaging:17.3.4"

另外，请注意，在项目的根目录下，build.gradle我正在使用以下google服务版本com.google.gms:google-services:4.2.0。

我尝试了几种方法，分析了依赖关系树，不包括提到程序的模块，但是它们最终在运行时崩溃。我发现最安全的解决方案是15.0.1将firebase-ads

重建应用程序后，今天出现了上述错误，好像新的更新classpath: 'com.google.gms:google-services:3.1.0' 为

classpath: 'com.google.gms:google-services:3.2.0'

帮助解决了我的问题。

此外，本文中提到的其他答案也可能有所帮助，这取决于所使用的google com.google.firebase软件包的版本，我试图将firebase软件包更新为最新版本。您也可以参考以下问题，并从提到的答案中获得帮助。

allprojects {

2.将firebase依赖项更新到最新版本

如果使用任何依赖项，请更新以下依赖项。请注意， firebase现在为每个依赖项提供了单独的版本。

使用最新的Firebase库。在回答时，最新版本如下。

3.不要忘记Google插件

同样不要忘记apply plugin: 'com.google.gms.google-services'在应用程序级别build.gradle的底部添加。

同步和构建...
